A pipeline sealing sampler for oil refining and chemical industry

Abstract

This utility model provides a sealed sampler for pipelines used in oil refining and chemical industries. Its structure includes a sealing positioning tube, a connecting tube, a valve, a sampling connector, and an intelligent quantitative cap connected to the pipeline. The connecting tube is horizontally positioned on one side of the middle section of the sealing positioning tube. During installation, the sealing positioning tube is inverted and installed on the bottom surface of the oil refining and chemical pipeline, so that the intelligent quantitative cap is at the bottom. During sampling, a controller operates an appropriate number of electric push rods. The more electric push rods operate, the larger the sample volume. The electric push rods drive the sealing rod to retract. During retraction, the sealing ring of the second sealing disc is released, allowing the sample to enter the sampling chamber through the sealing ring. After a certain period, the electric push rods drive the sealing rod to reset. The sample passes through the connecting tube and is finally output through the opened valve. This structure is durable and not easily clogged.

Description

Technical Field

[0001] This utility model relates to the technical field of pipeline sealing samplers, and in particular to a pipeline sealing sampler for oil refining and chemical industries. Background Technology

[0002] A pipeline sealed sampler is a specialized device used to extract samples from pipelines in a closed environment, primarily in the petrochemical and other hazardous chemical industries. Its core function is to ensure that samples are not contaminated during the sampling process through a sealed design, while simultaneously preventing the leakage of hazardous substances.

[0003] Existing pipeline seal samplers adjust the sampling volume using flow control valves. However, for high-viscosity media, media containing solid particles, or media that are prone to crystallization, these valves are easily clogged or worn, affecting the adjustment function and shortening their service life.

Its structure includes a sealing positioning tube, a connecting tube, a valve, a sampling connector, and an intelligent quantitative cap connected to the pipeline. The connecting tube is horizontally located on one side of the middle section of the sealing positioning tube. The valve is connected to the end of the connecting tube away from the sealing positioning tube to control the opening and closing of the connecting tube. The sampling connector is located at the output end of the valve. The intelligent quantitative cap is detachably connected to the top of the sealing positioning tube.

[0007] The intelligent quantitative cap includes a cap body that is threadedly connected to the top opening of the sealing positioning tube, and a drive seat located on the bottom surface of the cap body and embedded in the sealing positioning tube. The bottom surface of the drive seat is vertically provided with several electric push rods, the output end of the electric push rods facing downwards, and a sealing rod is provided.

[0008] The sealing positioning tube has a first sealing disc in the middle that is movably and sealingly fitted to the upper part of the sealing rod, and a second sealing disc in the bottom of the sealing positioning tube that is movably and sealingly fitted to the lower part of the sealing rod. A sampling chamber communicating with the connecting tube is formed between the first sealing disc and the second sealing disc.

[0014] In one embodiment, for ease of control, the valve is specifically one of a solenoid valve, ball valve, butterfly valve, electrically actuated valve, or flow regulating valve.

[0015] In one embodiment, to improve the sealing performance of the connection, the first sealing disc and the second sealing disc are the same shape and size, and are integrally formed with the sealing positioning tube.

[0016] The advantages or beneficial effects of the above technical solutions include at least the following:
